ML-20 Artillery Tables

Continuing my collection of artillery tables, the model 1937 ML-20 gun-howitzer, which found a home in the SU-152 and ISU-152 Soviet SPGs. The ML-20 could fire several different types of ammunition. Here is the table for the BR-540 armour piercing shell:

The table confirms the impressive dispersion results from the test I posted: 20 cm vertical and 30 cm horizontal at 1000 meters.

The next shell type is the naval high explosive semi-AP shell. At 1000 meters, it has the same dispersion as the AP shell.

Next is the OF-540 high explosive fragmentation long range steel gun grenade. Its scattering is much greater: 30 cm vertical and 70 cm horizontal at 1000 meters. This table has much greater ranges than the AP ones, capping out at over 17 kilometers.

Next is the concrete penetrating G-53 shell. It shares its table with the OF-530 high explosive fragmentation long range steel howitzer grenade and O-530A long range steel-iron grenade.
